Stud ends in accordance with this part of ISO may be used at working pressures up to 40 MPa [ bar1 ] for non-adjustable stud ends and 31,5 MPa bar for adjustable stud ends. The permissible working pressure depends upon the stud end size, materials, design, working conditions, application, etc. Conformance to the dimensional information in this part of ISO does not guarantee rated performance.

Each manufacturer should perform testing according to the specification contained in this part of ISO to assure that components comply with the performance ratings. NOTE 1 A significant number of tests have been conducted to confirm the performance requirements of connection ends made from carbon steel.

NOTE 3 The Introduction of this part of ISO gives recommendations for ports and stud ends to be used for new designs in hydraulic fluid power applications. Central Lubrication Fittings.
